餐厅呼叫系统设计 摘 要:近年来，许多中高档餐厅逐渐采用无线呼叫系统完成顾客的点餐及各项服
务内容，大大提高了餐厅的服务质量和工作效率，及时安排顾客用餐。另外无线呼叫系统的铺设和维修比传统的有线呼叫更为方便快捷，也可以广泛应用于医院，工厂等场所。
本设计是基于51单片机的远程呼叫系统，利用无线通信技术传递信息，并实时显示，实现各餐桌对服务台的无线呼叫。该系统包括客户端和服务台端，客户端可以实现餐桌对服务台无线服务呼叫和结账呼叫的功能，服务台端接收呼叫信息，根据餐桌号和所需服务项目安排服务员。本设计客户端由发射模块和按键模块组成，服务台端由接收模块，按键模块，显示模块，声光提示模块组成。对于客户端，当用户按下某个按键，芯片SC2262对按键信息进行编码，送给发射模块；对于服务台端，接收模块将接收到的信息送给解码芯片SC2272，进行解码，然后将解码信息送给单片机STC89C51，单片机对信息内容进行分析，并将桌号和服务项目通过数码管显示。当有两个及两个以上餐桌呼叫时，服务台会交替显示对应的桌号和所需服务项目，同时蜂鸣器和LED灯会进行声光提示。另外，客户端设有“取消”按钮，可以撤销本次呼叫，服务台端同时设有“清零”按钮。
经过编程，仿真和调试，系统最终制作成实物，经测试和运行良好，达到预期的效果。

Design of Restaurant Calling System
Abstract :This year,many middle grade restaurant gradually use wired calling system
to service the customer’s order,and it can improve the quality of service and efficiency,so as to arrange the customers to have dinner timely.Also,the wired calling system’s construction and repair is more convenient and quick than the traditional calling system,and they are widely used in some areas,such as hospitals and factories.
Tthis system is the remote call information base on 51 single-chip computer ,use wireless communication transfers information, and display on the digital tube,and ensure every table can call the service station. This design includes client and the service station,the client can realize the function of the table on the service station wireless service call and checkout call,the service station receives the calling information,according to the table number and the service ,than arrange the waiters. The client consists of transmitting module and keyboard module,the service station consists of receiving module,keyboard module,display keyboard,sound and light warning module.To the client,when users press a key,the coding chip SC2262 in the client encode the key information,and send it to the transmitting module.For he service station,the receiving module send the information to the decoder chip SC2272 to decode the information and send it to the MCU STC89C51 ,MCU analysis the information and estimates it.and finally display the information on the digital tube by digital driving.This information reflects the table number and service content required,When there are two or more table call the service station,the service station alternately display the table number and the service content,at the same time,the buzzer sounds and the LED light tips.Also,the client has “cancel button”to cancel the calling,the service station also has”zero button”to zero the system.
After programming,simulation and adjustment,the system finally is made to the object.After testing,it is running smoothly,and reach the desired results. Key words: MCU;Wireless communication;Restaurant calling;
